Abstract [en]

Models showing the anthropogenic and natural flows of two sustainability indicators; carbon based GHG and energy (as work energy) have been made for the Swedish region Jämtland. The methodology used was inspired by the study sustainability analysis conducted on the small Danish island Samsø using the above two indicators. The aim was to upscale the methodology used for Samsø and make necessary adaptations for Jämtland in order to be able to evaluate sustainability in terms of global warming. We also wanted to study the linkages between research, education and regional sustainability initiatives. Working at a regional level has advantages compared to working at a national or global level, as socio-ecological processes can be covered more extensively to reach a deeper understanding of practical aspects. In parallel to this we have also been participating in local and regional sustainability activities to increase our understanding of practical approaches and human behaviour.

Studies of the energy flows in Jämtland show that 46,000 TJ (88% renewable) flows into the region and about 31,000 TJ is exported. The remaining 15,000 TJ (63% renewable) drives ‘the machine Jämtland’. Added to this is about 4000TJ as matter. The total global warming potential (GWP20) impact of Jämtland (as carbon dioxide equivalents, CO 2eq ) indicating influence on the global mean temperature as radiative forcing) is an annual uptake of 2.4 Mton. The total regional emissions, as CO 2eq, from anthropogenic activities, including consumption, are 1500 kton. The region has large emissions of methane, 80kton (6700 kton CO 2eq ), mainly from mires, lakes and animals but also large uptakes of CO2 from assimilation in woody biomass.

Jämtland can be regarded as relatively sustainable from several perspectives, but taking the large forests and a population of only 127,000 inhabitants into consideration, the total uptake of CO 2eq is not very large and of the 15,000 TJ driving Jämtland, 37% comes from non-renewable sources. From a national (and global) perspective Jämtland needs to perform better, in view of its considerable reserves of natural resources. How to increase long-term sustainability in the region is a complex issue that requires penetration from many perspectives. Modelling results presented here needs to be interpreted in a broader sustainability context, together with regional stakeholders, to serve as a base for future knowledge development and sustainability activities.

Abstract [sv]

Två modeller har utvecklats för att studera antropogena och naturliga flöden av energi (exergi) och kolbaserade växthusgasflöden i Jämtland. Metodiken har inspirerats av en metodik för att göra hållbarhetsanalyser som genomförts för den lilla danska ön Samsø utifrån dessa båda indikatorer. Att arbeta på regional nivå har fördelar gentemot att arbeta på en nationell eller global nivå eftersom man har större möjligheter att gå ned på djupet både gällande samhälleliga processer och ekologiska processer. Kopplingen mellan siffror och faktiska skeenden blir tydligare. Parallellt med arbetet med de regionala modellerna har vi också deltagit i lokalt och regionalt arbete för att förståelsen omkring praktiska angreppssätt och mänskligt beteende.

Studien av energiflöden i Jämtland visar att 46.000 TJ (varav 88% förnyelsebart) flödar in i regionen och 31.000 TJ exporteras ut och att resterande 15.000 TJ (varav 63% förnyelsebart) driver maskineriet Jämtland. Till detta kommer omkring 4000 TJ i form av material. Den totala GWP20-påverkan från Jämtland är ’kylande’ och motsvarar ett upptag av koldioxid-ekvivalenter årligen på 2.4 Mton, vilket ungefär motsvarar emissionen från225.000 genomsnittssvenskar. De totala antropogena emissionerna av CO 2eq , inklusive konsumtion, är 1500 kton. Regionen uppvisar betydande emissioner av metan, 80 kton (motsvarande 6700 kton CO 2eq ) från sjöar, myrar och våtmarker samt djur.

Jämtland kan ur flera perspektiv betraktas som relativt hållbart, men tar man de enorma skogsarealerna och den i ett internationellt perspektiv blygsamma befolkningen på 127 000 personer i beaktande är hållbarheten mindre övertygande. Vidare är 37% av den energi som driver Jämtland faktiskt icke-förnyelsebar. Sett ur ett globalt perspektiv och med hänvisning till Jämtlands enorma naturresurser behöver Jämtland prestera bättre. Hur man skall kunna öka den långsiktiga hållbarheten är en komplex fråga som kräver belysning från flera olika perspektiv. Resultat som de som presenteras här måste tolkas tillsammans med regionala intressenter i ett bredare hållbarhetssammanhang för att kunna utarbeta lämpliga implementeringsstrategier.

Abstract [en]

An analysis of energy and material flows has been elaborated for the Swedish region Jämtland with the aim of monitoring and comparing regional sustainability by following the work energy flow method developed in a study of the Danish island of Samsø (Nielsen & Jørgensen, 2011). In the region of Jämtland about 46,000 TJ of energy flows into society, of which 88% is renewable. From this an amount corresponding to 30,800 TJ is exported as electricity from the region, while another 410 TJ is exported as waste to be incinerated. The remaining part, about 15,200 TJ (63% renewable), drives Jämtland. From an energy flow perspective, the most important production from the region, apart from electricity production, is biomass from the forest: 49,000 TJ estimated as energy content in the biomass harvested. Another 55,000 TJ is added to the standing biomass every year as forest growth (only productive forest land area has been calculated). Some suggested indices of sustainability have been calculated and Jämtland shows high values. However, it will be a challenge to transform the quite large transport sector of Jämtland, and therefore the potential to become fully sustainable (ref to indexes used for the Samsø study) might not be quite as high. In order to reduce the use of non-renewable energy, a major conversion of the transport fleet is needed, and this should be given high priority. The private sector is the largest single user of non-renewable energy (2,200 TJ). One successful transition is the Swedish diesel mix with 19% FAME/HVO derived from vegetable or animal sources and regarded as renewable. The consumption of FAME/HVO is predicted to increase significantly, increasing the importance of the forest as a source. A sustainability analysis based at work energy flows shows for both Samsø and Jämtland that large natural resources producing a high work energy output combined with low work energy use due to low population density, gives high sustainability indicators. This indicates that regions with high population density and the absence of natural resources (high import), as in most regions in the world, will show low sustainability indicators.

Abstract [en]

In May 2015 A4 Campus AB made a 30 kWp solar cell installation in cooperation with Mid Sweden University at one of the university buildings in Östersund. Four different types of solar cells were being installed each type with a power of about 7 kW; two types of polycrystalline silicon panels, one monocrystalline silicon type and one thin film (CuInSe2) type. The three types of crystalline panels were equipped with individual optimizers making individual panel follow up possible. A one year evaluation shows the installed thin film panels produces more electricity (as Wh per installed W) than do any of the installed crystalline types. The efficiency of the thin film panels is relatively higher compared to the crystalline panels those days when the insolation is lower, which might indicate future climate change should be taken into consideration when choosing which type of solar cells to install (for northern Sweden more rain is being predicted). Each one of the crystalline types are installed as a matrix with 2 or 3 rows. The lowest rows of each type produces more electricity compared to the row above. This might be caused by an increased temperature of the air flow behind the panels. However, during the period November to April the production especially of the lower rows is reduced due to snow coverage. For multiple row installation this phenomenon should be taken into consideration for calculations for optimal layout (1,7-1,9% reduction per row for 3 rows).

Out from the follow-up made it can be seen that the evaluation of offers from different manufactures is rather complex and the yearly production cannot be easily calculated of from the specified efficiency. A 6% difference in power output from crystalline types can be seen at an insolation close to 1.000 W/m2 and the difference in efficiency given in the specifications is in the range 15,2% to 15,8%.

Abstract [en]

In his book “Environment, Power, and Society” (1971) H.T. Odum introduced a picture of the energy metabolism of a city based on Wolman's paper from 1965 (Sci. Am., 213: 179-190). With the development of the emergy analysis--a branch of energy systems accounting--several authors have contributed to develop quantitative measures of HT Odum’s picture, which from many perspectives are diverging from traditional energy studies. In this paper, studies using emergy analysis to study cities are reviewed. The research regarding emergy and cities had during the period 1975-1995 its focus on cities in the United States, e.g. Miami, Jacksonville, San Francisco and Chicago. The research during 1995-2005 was almost exclusively focused on Taipei. From approximately 2006 up till 2015 the research focus has been on Chinese cities; Macao, Beijing and 37 other Chinese cities have been investigated. But there are resent also studies made on Rome (Italy) and Montreal (Canada). Studies up to about 2007/2008 were generally concerned with understanding spatial aspects of the cities investigated. After that, evaluating the sustainability of cities has become a main research focus.

Abstract [en]

The purpose of this paper is to present a pilot educational project where ecological modelling has been used to integrate advanced level students into the research about regional sustainability. Addressing regional sustainability with an ecological systems model based on carbon and energy balances is a way to understand the basics of sustainability integrating detail and holistic views. Such model has been developed in a case study on the Danish island Samsø, and currently a similar model is now being developed for the Jämtland county. Even though Jämtland, located in mid Sweden, is a sparsely populated area with large forests, a lot of hydro power, and only one major city, it is still not obvious how to reach long term sustainability. For educational purposes ecological models are excellent tools, since complex interactions can be studied, analysed and discussed in a structured way. It can be expected future sustainable society development presupposes integration between research and education, thus building a long term strategy for the possibilities to change negative cultural patters of whatever kind these might be. To strengthen the authorisation of the education for sustainability, clarification of the university’s integrative role in society may well be used, to give students self-confidence for continuous development within the field.

Abstract [en]

There is a variety of definitions of the concept ‘sustainable’ to be found, and many interestingideas how to measure and evaluate what can be regarded as ‘sustainability’. Meanwhile,whatever the definition is used it must have a strong physical background. There is also acontinuous flow of information and a general awareness about the necessity of taking action,thereby reducing the negative anthropocentric contribution to global warming and ecologicalsystems depletion. A number of visions about (for example) future emission values typically 15-30 years from today are often presented. At the same time there is a continuous political debateabout the balance between individual freedom vs political regulations. The typical individual -standing in the intersection of all this - still seldom gets practical guidelines on how to act in thedaily life to meet future visions. This paper argues that it is necessary to simplify the indicatorsused to evaluate sustainability and at the same time ensure clear instructions of action therebyincreasing the communicability. This is believed to be possible through the application of aholistic approach based upon a detailed mapping, thus making it possible to find out an over-allstrategy and then transform it into specific guidelines for the individual to apply, taking anentrance point in a realistic description of individual everyday life. The regional level is chosenas the most suitable level to work with to keep in touch with the individual level without losingthe strategic possibilities and over-all view when attacking the problem. Without a deep andcommon understanding of the ‘daily life’ in the region, visions and guidelines might show to becounterproductive.For the Swedish region Jämtland, a sparsely populated area with large forests, a lot of hydropower, and one major city (Östersund with about 60.000 inhabitants), some industries and skiresorts (the largest being Åre), the method developed by Nielsen and Jørgensen for the minorisland named Samsø in Denmark has been chosen. By building a model for evaluating thecarbon balance and the work energy balances we are able to focus the strategies and make aguideline for individuals. It seems necessary to accept some usage of fossil fuels also in thefuture but we need to see how this usage can be steered to applications where non-fossilalternatives are less realistic. By working with sectors, built together, we are able to work withsub-models without having to compromise on either lower or higher level of societal activities.Compared to the Samsø case, Jämtland is more complex and also much larger (127.000inhabitants compared to Samsø’s 4.000 and with an area about 20% larger than theNetherlands). The sectors chosen are Industry (Businesses other than those covered in othersectors), Agriculture, Forestry, Tourism, Nature, Public, Private (households), Reindeerherding, Wastes and Energy. The budget of each sector is mapped in terms of carbon and workenergy balances as a sub-model of an over-all model of Jämtland. By finding out the limits(constrains) from simulations carried out on the region it is possible to set for example carbonand energy budgets as basis for personal guidelines for the citizens of the region.The major idea is that most citizens of the region will understand and adapt to such guidelinesto an extent that may induce a change of individual behavioral patterns thus turning the regiontowards sustainability. Jämtland has a specific “culture” which can be used to create proudnessand interest for the sustainability aims. It is important to arrange a platform that serves to shapea fruitful dialogue between all stakeholders – from individual to groups – that will make itpossible to create a common plan for measurements to be implemented, i.e. a concertedgovernance which ensure and guarantee a future of optimal existence for ecosystems as wellas human beings.

Abstract [en]

The global development has now come to a critical state where humanity act as a new geological force and it is obvious that there are numerous of environmental problems which arise from the present geosphere-biosphere-anthroposphere interactions which urgently need to be addressed. This paper argues that systems analysis and modelling of environmental systems is one necessary part in successful governing of societies towards sustainability. In the 1960th many observations and data made it evident that the environment in most countries was in a bad state. To get a holistic view of the complex problems and to clarify the relationships of structure and function, systems thinking was applied e.g. modelling, cybernetics, systems analysis, life cycle assessment and energy and material flow analysis. Such tools used collectively, conceptualized as ‘integrated assessment’, can help to communicate fundamental knowledge, and to support decision-making when identifying, developing and implementing precautionary measures and solutions. There are good examples demonstrating the strength of such approaches; Solutions to the ozone depletion by replacing CFC’s with more chemically reactive compounds that are degraded within the troposphere. Acidification of European low buffer soils and lakes, sensitive to acid rain, has decreased due to concerted action on Sulphur emission control in large parts of Europe. The handling and recycling of solid waste has resulted in a considerable reduction of deposits in large parts of the world. This basically natural scientific knowledge has also influenced the development within e.g. economy and jurisprudence and today ecological economy and environmental law assume ecological systems as fundamental.

The complexity of ecosystems and environmental issues can only be understood by use of advanced scientific tools such as modelling as a base for establishing interdisciplinary co-operation. Each component of such models will of course be an approximation, but validation and verification of the models will serve to make them useful. An ongoing research project at Mid Sweden University aims at building a complete carbon and energy balance model of an entire Swedish region, based on the Danish Samsø-model. Such models will make it possible to refer to a robust scientific base, thereby making it easier to argue for appropriate measures and actions. At the same time it will be clear what data these actions rest upon thereby making it easier to identify possible errors or limitations.

Systems analysis and subsequent modes are constructs. According to systems theory and model development they are strategies as the best representations of nature, we can make. At the same time it must be assured, that a continuous adaptation and improvement in a studied area is possible - i.e. that model outcomes are matched with phenomenological observations and that empirical work also is carried out. Model development can therefore be characterized as a dynamic and iterative process.

Governance in the Anthropocene must be based on an understanding of the problem picture at hand, and learning how to appropriately address increasingly complex issues. For identifying potential solutions and consequences of policy implementation, systems modelling on relevant levels will be one necessary tool. The current project developing an environmental regional model, illustrates how modelling can provide decision support for the county of Jämtland regarding management of energy resources and planning of future infrastructure, as well as serving regional and national information purposes.
